Carry optics build, Glock 45 vs 17 vs 34

Recommended Posts

I have a Glock 34 gen 4 that I use in production, however I've been wanting to try carry optics. I'd like feedback on what to buy for the purpose.

 

Choices are:

1) brownells RMR cut Glock 17 slide and put it on my 34 frame

2) glock 45 mos

3) gen 5 Glock 17 mos fs

4) gen 5 Glock 34 mos

 

Today I handled (but did not shoot) a Glock 45, it was my first time holding a gen 5 and I really liked the upgrades. It seemed to me that the new gen 5 trigger is quite a bit nicer than the gen 4. It's a more significant difference than I had expected. I also liked the magwell flare. For that reason I'm leaning towards purchasing a new gun rather than an optic-cut slide for my 34.

 

However, I'm kind of stumped as to the ideal barrel length for carry optics. Although the sight radius won't matter with an optic, there are still differences in cycle time, balance and perceived recoil between the 3 slide lengths. I know some people prefer the longer slide even with an optic as it feels smoother, but others have said that a shorter slide is an advantage because you have a shorter cycle time and the dot snaps back on target faster (if you have good grip).

 

Does anyone have experience with the 45 or 19x? Is there much difference in feel versus the 17 or 34? What's the latest thinking on slide length for a red dot pistol?

 

Feedback much appreciated, thank you.

Dont think or didnt think they offered a G45 in a MOS version.  None the less I dont think you would want the 19 size slide for CO, at least I wouldnt. Minimum of a G17 length

The 45 MOS was just released at the NRA annual meeting and has already shipped to dealers.

 

Why do you say the 17 slide length should be the minimum? Should I get the 34 gen 5 mos? If so why?

Pretty sure that putting a 17 slide on a 34 frame is illegal.  I would go with a 17 as well. little shorter but the barrel length will make it a little easier making power factor.  That is unless you like the feel of the 34 better then i would go that way

Hello: The Glock 17 and 34 use the same frame. I like the Glock 17 length slide for Carry Optics since it transitions quicker for me and gets back on target faster for me. Using the same load in a G17 and G34 the power factor is only 3 difference. So G17 is 131PF and the G34 is 134PF. I have owned both and sold the G34 MOS and kept the G17 with the Brownells RMR slide and a Holosun 507C on top. Thanks, Eric

I shot the 19x and hated it. Grip was nice, but idk it just felt extremely snappy.

I was heading towards the 17, but the extra ounce or two from the barrel pointed me to the 34. Also, if I didnt stick with CO, I was going back to prod.

 

I dont think you can go wrong with the 17 or the 34. You might get a split second faster draw with a 17, but Its negligible on most stages. Since you have a production setup already though, I dont really think it matters which length you purchase unless you decide to change your prod setup to go gen 5. 

 

Whatever you do, get the FS versions. The 34/17 FS is VERY nice, and has that small cutout by the magwell on the front of the grip filled in.

I like my G17 Gen 5 MOS slightly more than my G34 Gen 4 milled for DPP. Can hardly tell a difference.

No reason not to get a 34, IMO. No downside and you can shoot it in competition if you ever decide to ditch the dot.

 

I personally like the feel of the 34 better but everyone is different

If you want to ever shoot production with it then 34, if not 17. The 34 is just a tad too long and swings like you are swinging a baseball bat in comparison to the 17.

I shoot both 17 and 34 interchangeably. The weight distribution is different. The 17 is more nimble to move around and more snappy in recoil. But none of these makes a noticable difference in the scores.

Thank you for the replies, I think I'm going to try out the 17 gen5 as I already have a 34 (gen4). Hopefully it will prove a nice middle ground between the long slide and the 19.

The 34 will be the softest shooting of the Glocks. You will get more velocity with less powder and a less violent cycle with the longer and heavier slide. This should result in easier sight acquisition and a longer life for your dot.

You will be happy with your choice. Especially the way better ejection of the Gen 5. Don’t have to worry about your optic batting the brass during ejection like the Gen 4.

Picked up and shot the 17 yesterday. First time shooting a 17 or a gen 5, and it was a pleasant experience. I think I actually prefer the gen4 grip with finger grooves, but I do like the slight magwell flare and the trigger is better out of the box.

 

Now I need an optic! SRO, DPP, or wait for the sig Max?

Depends on how patient you are. 

 

SRO last I heard just got pushed back until June, I have no clue when the Romeo Max is coming out. 

 

Id pick up a new or used DPP to tie you over unless you want something like a Vortex venom/FF3. I think @Rich406 still has a used DPP left for $280

I'm patient, I'll continue to shoot production or PCC until one of them hits and the initial bugs are uncovered. I'm sure Holosun will eventually release a larger window version of the 507 too.

 

I thought the SRO was shipping already and the Romeo 3 Max was projected for july, but I would certainly believe that either or both could get pushed back. Making a dot durable enough to ride on pistol slides is hard.

There were a few places that were supposed to be getting shipments this week but I guess that all went to hell.

The sight radius is obviously a non issue but the added velocity of the G34 vs the G17 is marginal but is still relevant. Plus If you decide to run the same pistol in production I believe you would much prefer a G34 or G17.
