I realize I can't really go wrong with either pistol, but any objective advantages to a Gen 5 G-17 MOS versus the Gen 5 G-45? Either weapon would be carried concealed with a TLR-7A and an RDS. I realize the G-17 would be slightly less comfortable in an IWB, but I carried a SIG 226 that way for a quarter century. Thanks and be safe.
It may have cost a little more to get the RDS mounted, but I like my G45 that was milled by DP Customs way better then my Gen G17 MOS (even with the CHPWS plate).
If you don’t have a restriction on it (my Gen 5 G17 MOS is a duty gun - can’t get an issued gun milled so if I want a dot, I’m stuck with MOS) avoid the MOS and send the slide out to get milled for a direct mount for your chosen optic without the need for adapter or mounting plate. Simpler solution and mounts the dot lower in the slide
If you’re comparing a Glock 17 MOS to a Glock 45 MOS, I would say that there is t and advantage to going with the 17 over the 45. Especially with the light you plan on using. The longer eight radius of the 17 is negated by the optics.
I’d rather go milled but the MOS G17 I ordered will get the Forward Controls RMR MOS plate.
I subjectivity liked my G45 better than my G17 in factory configuration, once I put an aftermarket guide rod in the G17 and re-sprung it I think it’s maybe better with my reloads? I has a G19MOS top end on the G45 for a while with an ACRO and then put it on one of my G17MOS that was factory sprung, can’t say I’ve really noticed much of a difference... There may be a bit of difference in the cycle time if you shot them back to back but it’s going to be small and if you start messing with springs that may even out, the only other thing that may make a difference is the G45’s slightly lighter slide that will have a bit of an effect on the reciprocating weight.
I slightly prefer the balance of the G45 when loaded. I am however switching to VP9 which is what I shoot the best.
I know this is subjective, but the trigger in my Gen 5 17 is a hot bag of trash compared to my G45. I put a Glock Triggers kit in the 17 to improve it, but my 45 is better with only a minus connector. That said, I would argue that the 45 is the best pistol that Glock has ever made, and would carry it on duty if we were allowed. I also carry the 45 with a TLR7 on it, as opposed to the Uboat on my 17.
