    Choosing Extended Mags in USPSA P?

    As per title, would you chose to use extended magazines in USPSA Production, even though one is limited by rule to 10 rounds in the magazine at the start? I shoot production, so I am forever reloading between target arrays. It's not uncommon for me to see the mag fail to drop free, or the botch a reload (I have Medium size hands) on drawing the mag from the belt, or on inserting.

    Case in point: Here is my G19 I use in USPSA. This shows a G17 mag inserted, with a Dawson basepad. (I use silver on this basepad, as opposed to the rest, which are black, so as to tell which mag I load with 11 at the start) The rest of my reloads currently are G19 mags, with black Dawson basepads.

    Are there any downsides to using the longer mag?

    The weight of the 17 mag is 3.1 oz empty; a normal Gen 5 Glock 19 mag is 2.5 oz. I realize that, barring air, or friction, the extra weight should theoretically not drop faster. But would it or would it not overcome the surface of the inside of the grip quicker? Another consideration is just physically gripping the mag, both on reloads from the belt, as well as ripping it out of the magwell. It would seem the longer mag would help in both cases?

    While pondering this, I took some Flitz and rubbed down the outside of the mag tube, so the polymer is nice and smooth, then reassembled the mag. Bottom line, I'm likely ordering a bunch of G17 mags and dedicated a set to USPSA, exclusively, but wondered what the collective thought about this plan.

    Your thoughts?

    Iíve done it. It works fine, and given the cost of production legal base pads you might as well invest in a G17 mag IMO.

    As a guy that has used a G19 & G17 in USPSA I would suggest getting a G17 if you can afford it. If you stick with gaming youíll probably do it later anyway. Or a CZ 😀.

    @RJ, yeah a G19 in Production is a bit of an uphill battle. I'm not going to try very hard to talk you out of shooting it, and you're already aware that it has some disadvantages.

    Do you find that your 17 round mags and mag release get buggered from repeated insertion? If you're gentle with your mag insertions, it should be ok, but when you slam one in that's a lot of force on the mag ledge and release. Sig p320s can be permanently damaged by over insertion of mags (bends non-replaceable ejector).

    I would be more inclined to use a longer mag extension on a G19 mag if you are trying for longer mags. But if that's the problem, maybe you need a bigger gun?

    Sidebar...What makes a 19 an especially uphill battle?

    I mean... compared to one of the big heavy metal guns, yeah. But really compared to any other reasonable poly striker gun?

    If someone wants to get serious (or even semi-serious) about USPSA, my advice is to look at what the top shooters use and do. There are a lot of GMs who donít get free guns and donít get paid to use a particular one. I donít see any of them with a G19 size gun.

    As weíve discussed at length in other threads, index is critically important. Itís just easier to confirm index with a longer gun, and that alone would be enough for me to choose a G17 or 34 size.

    Recoil is typically easier to manage with a bigger, heavier gun.

    Ergos, mag changes, etc. are usually easier with a bigger gun.

    However, when Iíve run drills and stages with my P-07, the times and scores are often not that far off what I can do with a Shadow2. Yesterday I was torturing myself with 45 yd tuxedo and partial targets and small steel. Right on the edge of failure every run. No freaking way would I want to do that with my P-07.

    I shoot the guns that let me push my skills as far as I can.

    No worries. I understand. Appreciate the input. I should probably give some additional background.

    I bought the Glock 19 as a "one size fits all" carry/competition gun in 2017, as at the time we were both storage and budget constrained. So I still have it. I shoot it because I was (at the time) both carrying it as well as training/competing with it. With 6,400+ rounds through it, you could also say I'm emotionally attached to it () which might sound corny about a Glock, but it's true.

    I also failed to explain, a Glock 19 in my hand, looks like a Glock 17 in most other people's hands. I wear a size M but stubby fingers. I do not use a backstrap. So anything larger, really, is not a plus. I'm with you on the heavier gun; I added a brass plug and tungsten guide rod to give me +3 oz to my G19. I do notice the difference shooting it; it is much flatter in recoil. I did rent a G34 at the range a few months ago. It was cool but not the magic death ray of accuracy I was hoping for. Certainly can't argue the longer sight radius, though. Damn that thing was lonnnnnnnggg lol.

    Lastly, as you are probably aware, much more than me, what is preventing me as a D shooter from advancing is not small advantages gained by equipment, but by doing the work, avoiding errors, and getting trigger control down to put Alphas on targets, quickly. And not screwing up. And moving faster. And getting quicker on reloads. And not screwing up (I said that already, but it bears repeating)

    With only ever having shot 11 matches, in my lifetime, I need to get a lot more match experience. So this coming fall season, as I'm coming out of a transition to retirement, and COVID is opening up our local matches, I plan to start doing weekly local matches on Friday nights. Right now it's still pretty hot out (my laptop temp ticker is showing 97F, and it's 6:30 in the evening here in Tampa as I type this.) Hopefully end of Sep and into Oct things will cool off a bit.

    If I won the lottery, I'd buy a G34 and shoot it in competition, but I have been doing the carry gun shuffle the past year, spending time and $$$, and am about to do it one more (last?) time, by trading in in my P365XL (which I traded in a G43X for) for a Glock 48, and will keep the G19.



    To your points: I have yet to use a G17 magazine in a match. To date I've used G19 mags, hence the question. I do have issues in grabbing off the pouch, as well as them falling more or less free during transitions (I almost always reload while sprinting to a new target array).

    I had not thought of a mag extension on a G19 mag, that's a good idea.

    I do recall seeing the thread on over-insertion of a 320 mag causing the ejector to bend up. It's part of the reason I am trading in the XL; I had thoughts of selling the G19 for a 320, but threads like that disabused me of that idea. So, even as good a shooter as the P365XL is, I don't want to transition to a larger Sig for USPSA, leaving me with a Glock 19, and the decision to swap the XL for a 48.

    Anyway, thanks CF. Your opinions are always much appreciated, and make me think.

    At the risk of further derailing this thread...... and I agree with CF btw.

    RJ have you ever considered shooting Limited for a while? Why not simplify your life and reload less? Build some shooting skill then go back to Production.

    On topic: whether you use a 17 mag or Production extensions, it will help with seating mags in my experience.

    I may or may not have put in and removed a few Pmag 21 rounders in my Brownellís shopping cart.

    Truth: Iíd honestly like to make C class in Production first; me being stubborn I guess lol.

    @RJ Iím like you, I know Iím not going to win, and I enjoy shooting the gun I have. At several points in my life Iíve gone full hipster and bought into the idea that I *need* the new hotness (last time was a CZ that I might have shot in 3-5 matches tops, as well as all the other gamerninja junk like mag pouches, a dozen mags, etc) only to always come to the same conclusion... the limiting factor isnít the gun, itís me. Even when I *have* invested the time in various sorts of dry fire programs, rad all the books, did all the kool kid shit, the limiting factor has been me.

    And eventually I came to the realization that I just donít care enough about a score that maybe max 3 other people in the whole universe care about (me, the guy below me, the guy above me) in some silly game. Iím there to have fun. And if shooting some ďnon-competitiveĒ gun is fun for me then Iím going to do it. My whole gamer rig is basketweave. Why? Fun. And for every gamerninja that looks at me and thinks Iím some boomer loser, I look at them with my own ideas about their situation too.

    As to your original question, Iíve been gamering with a Glock 19 on and off for 15+ years, and I personally have always gotten the best results using G17 mags. Unlike you, the G 19 fills my hand quite well and I find the added length to be helpful for seating and other manipulations, including rare instances of stuck mags that I need to rip free. When I carry the G19 itís a 15-round mag in the gun and a 17-round mag in the pouch.

    I like your Barney mag idea of the fancy floor plate. If my newfound interest in gamer gunning continues and bleeds into handguns (Iím enjoying the shirt out of the gear-light world of PCC right now) Iíll have to adopt that one too.

    Oh, and Iíll probably also shoot production instead of Limited. (A) because less people are shooting it these days so I can be more competitive (like dorks that shoot revolver) and (b) because reloading is fun to me.
