Reviving an old thread because I got a gen 5 G19 and wanted to share initial impressions. I just got this from a fellow forum member, very lightly used with a few enhancements but no major internal changes. I've been shooting an MR918 and a pair of MR920s for a few years now, so I'm not unfamiliar with the platform. I added the medium beavertail backstrap and it fits my hand about as well as my Shadow Systems and points the same for all intents and purposes. I found the grip texture to be overly aggressive compared to the SS. It could use a little more undercut at the trigger guard.
The trigger is an SSVI Tyr. I had read a number of positive reviews on this one but I found the wider dingus to have sharp edges and it got irritating after about 100 rounds. I didn't find it to be a marked improvement over the SS trigger. My preference will probably always be the SA on my USPC 9 compared to any striker trigger.
I put a box of Fiocchi 115 grain through it to confirm zero of the 509t and then a mag of HST 124 +p with no issues but on the next box I had 4 misfeeds in fairly short order with the round only getting about halfway into the chamber. I was using gen 5 Glock mags and the misfeeds occurred with 3 different mags. All the rounds functioned properly the second time around and I ran a third box of 115 grn and a box of HST through with no further glitches. I don't hear of issues with 19s and I've not had problems with that ammo before. I was shooting dominant hand, two handed so I don't think I was limp wristing it, mags were fully seated, so I'm not sure what happened. I guess I'll run a few hundred more rounds of other ammo through it before I call it good but I find it disconcerting nonetheless.
The slide is milled by Jagerwerks for direct mount of the 509t so no adapter plate.
