calebj06 Posted April 30, 2017 Share Posted April 30, 2017 So I shot carry optics for my first match and loved it. I'm currently shooting a g19MOS with a vortex venom dot. So the 19 was purchased before competition shooting was in the picture. So now I'm thinking about getting something more geared toward competitions and it got me to thinking. Usuallly one would go with a 17 or 34 for uspsa due to a longer sight radius. But I'm shooting optics! So what would me advantages be of going to a longer gun? Especially since longer mags are not an issue with glock. A slightly larger girp? Little more velocity out of the barrel? Im just wondering out loud here. I know if I decide to go production or limited I'll get a 34 or 35 (or something different all together). This isn't really glock specific. I'm just wondering, why should I buy a longer gun if I'm not using the sights anyway? caleb Link to comment Share on other sites More sharing options...

ToddKS Posted May 1, 2017 Share Posted May 1, 2017 I prefer the balance and feel of the G17 over the G34. Personal preference. Link to comment Share on other sites More sharing options...
selecw Posted May 1, 2017 Share Posted May 1, 2017 Look at an after market milled slide vs the MOS... lower mounting and increased thread depth. Link to comment Share on other sites More sharing options...
cj36d Posted May 1, 2017 Share Posted May 1, 2017 Built an M&P core pro with a Leupold DP Pro. If I had it to do over again I would have gone with the new Sig P320 X5 with a Romeo 1. As to your question about long slide guns when using an optic...the fundamentals of design don't change when you bolt on a dot. Longer barrels equal more accuracy, consistent groupings, and more total mass which assists recoil management. Look at the length of a quality open gun...

I originally had a G17 that was my GSSF gun and Bought a G34 with intentions of building it for CO class, but a friend advised me to really shoot both to see if which one would feel best. Ended selling the G34 top end and kept the lower to be a back up for the G17. Link to comment Share on other sites More sharing options...

Accuracy doesn't depend on barrel length. (It might depend on sight radius for many people in terms of precision, but with a dot that's not an issue.) Similarly, "consistent grouping" doesn't depend on barrel length. Open guns tend to have longer barrels because it makes it easier to make major (longer barrel = more velocity). Similarly, it is easier to make Minor with low-power loads using a G34 compared to a G17. (As an example.) Mass, and placement of mass, I agree, can assist in recoil management (or at least change the recoil impulse). I don't believe I've ever run into anyone who said the longer barrel on their Open gun helped them be more accurate, or more consistent in their group sizes.

A lot of precision rifles are getting shorter...16-18" barrels. It depends on the cartridge how short you can go without losing too much fps. Barrel length doesn't have that much to do with the actual accuracy. Link to comment Share on other sites More sharing options...
zzt Posted May 15, 2017 Share Posted May 15, 2017 If I were going to shoot CO, it would be with a CZ 75 in one flavor or another. Recoil and muzzle rise are considerably less than with any poly gun. Link to comment Share on other sites More sharing options...
tdp88 Posted May 17, 2017 Share Posted May 17, 2017 I already have a G34 for production, would I be able to have it milled for an optic and just put a plate on if I go back to production? Link to comment Share on other sites More sharing options...

You should definitely mount your Optic to an M&P shield compact. Link to comment Share on other sites More sharing options...

You could just get a mount that fits in the rear sight dovetail... easy to go back.Sent from my iPhone using Tapatalk Pro Link to comment Share on other sites More sharing options...

You can't have it milled and go back to Production. You could buy a G34 MOS and go both ways. Link to comment Share on other sites More sharing options...

Primary Machine only has the RMR version stll available. To mill the EAA would probably get into the FP block, which I think you stll have to have in CO, if it came with one. I think my Limited Pro with a DeltaPoint on a Primary Machine mount is great. Wish I could buy another one just like it. 44.5oz.

I think BoD meeting minutes? It's out there for sure. I have been searching for this answer. I have two CZ 75's milled for optics and CO division. I have asked around and searched forums for an answer. I finally broke down and bought a new slide for one of them to use as a backup gun for my Production CZ 75. It's not that I don't believe you, but if challenged I (the shooter) have to provide proof of eligibility for a plate covering the milled surface. It makes total sense that I can do the same thing the manufacturer can do, but I have no documentation. I am pretty darn good at reading all BOD minutes and I have never seen this. If you find it again please let us all know where. Link to comment Share on other sites More sharing options...

tyman1876 Posted June 26, 2017 Share Posted June 26, 2017 I use a G17 but I have big hands so it fits me better. If you shoot a G19 well then I don't see any reason to not run that. Link to comment Share on other sites More sharing options...
