Glock 17 MOS vs. Glock 45 MOS

[HCM]

17 because it is the icon and objectively better performing...unless you personally prefer the more brisk, snappy recoil characteristics of a 19, it's lower weight, or less material bulk iwb/more body and seat clearance while sitting & driving...

I'd only go shorter barrel & slide to get into a smaller grip model but it's all nitpickin' to be honest lol.

45 as a gen4 would have been more interesting to me since gen 3/4 19's didn't fit my hands.

John,

I think the G-45 tracks and shoots flatter. Sight radius, etc. aren't critically affected. I've had a long time association with the G-17 and in fact took one to that Metro Dade training you and I attended about an eon ago! I just think the G-45 has been an improvement on this great standard.

My experience with a G19X and a 45 MOS matches Wayne’s. For reference I’ve carried a 17.4 by choice at work for 8 years.

I prefer a full sized grip but I can’t relate the “Brisk snappy recoil” comment re: a G19.

My Agency is currently issuing the P320 in an X carry configuration. We tested compact (G19 size), Carry and full size across a range of shooters. performance on the clock was best with the Carry (G45 size).

I EDC a 19X and shoot a G45, primarily AIWB in a G17 holster from JM. My primary G45 is over 20k rounds now. I'd have to check the book but I think that's still 20k without a stoppage that wasn't induced or expected. Quantifying differences on the timer and target I've found the G45 will have a slight edge on the 17 depending on the shooter. Sight radius difference doesn't materialize and is mitigated by sight choice. Running hard, it is more comparable to a 17 than a 19 but has a flat and fast feel all its own. Balance and function with a WML is good. G45s with RDSs run well but I don't have their data. I've seen some agency/unit transitions from G17/G19 to G45 or G19X as standard, with more planned or pending.

G17s are still GTG and a standard to judge others by, but I won't buy another one. There's no reason to.

In Carry Optics with a dot, I see a pretty even split between the 17 and 34, but have yet to see a G45 with a serious competitor.

I think the differences are minute and will be shooter dependent.

With that said, I like the g45/19x as you can swap slides and gives me the option to have a cut down 19 grip.

You could have 3 pistols that all interchange and would cover pretty much all your needs except maybe a dedicated competition gun.

My work gun is a Glock 19 Gen 5, my home gun is a Glock 17 Gen 5 MOS (well, that one is being vetted still, at this time it's still my 17G4). A local agency just adopted Glock 45 Gen 5 MOS. So I've had time to mess around with all 3 variations in size.

I like the 17 better for full size belt carry or home defense/competition purposes. If I had to spend significant time carrying concealed or sitting in a car, I'd like the Glock 45 better. Both are pretty great.

Reviving a bit of an old thread:

What if you were carrying with a full size WML X300 in a duty holster? The holster likely is the same for a G45MOS and G17MOS since the light extends past the slide. Would that make any impact to which is preferred?

I ended up purchasing a G45 with RMR. I may still get a G17, probably MOS in case I do put a RDS on it. I definitely prefer the full size grip though, since I'm still trying to adjust to the RMR, I'm not sure which weapon I shoot better..

I thing the G45 is the perfect base gun for a Roland Special build. Fits G34 length holsters.

Actually, some duty holsters, made for pistols with WMLs, including the WML-compatible version of the Safariland 6360, have a piece that engages the muzzle, so, a G45 and G17 would use different holster SKUs.

JSGlock34 just posted an obvious example of why one may opt for a G45.

Another factor favoring the G19x/G45 would be the expedited clearing of the holster, during the draw, if the one pistol also served as a concealed carry weapon, in a holster that rides comparatively higher on the body. It may seem to be a minor difference, but many folks have shoulder and/or wrist articulation issues, as they age, or due to injury, and if a G19/G19x/G45 is already at the edge of what is possible, that extra fraction of an inch might matter.

Listen to all of these guys.

I went with the 45 MOS to slide swap with a 19.5 non-MOS frame.

No other reasons.

Personally this is one of the main reasons I went with a g45. That way I have a battery of gen 5s that slides/frames/parts can be swapped back and forth. I vastly prefer g45s full-sized grip but have the option of a g19.
