Craig N Posted December 4, 2012 Share Posted December 4, 2012 I wanna build a Glock Open gun to run 9mm Major. My part list is as follows for a G34 1) SJC 11 port comp/KKM barrel 2) Dawson hardchormed brass magwell 3) C-More STS and dovetail mount (slide ride) 4) Glockworx Stainless Steel recoil rod and 14 lb spring 5) Mag release with a button on it 6) Slide racker that replaces the backplate (from Brownells) 7) 4 Taylor Freelance +8 (+10 in 9mm) on new glock mags 8) DAA Racemaster and pouches/belt Anyone see any holes in my plans or have any advise as to what to change or add. I'm basically just trying to get one outta the gate with "bolt on" DIY stuff. Link to comment Share on other sites More sharing options...

Xfactor Posted December 4, 2012 Share Posted December 4, 2012 What about an upgraded trigger? Link to comment Share on other sites More sharing options...
Craig N Posted December 4, 2012 Author Share Posted December 4, 2012 One question. Have you fired a Glock Open gun @ MAJOR PF? No but I have shot a few 38 supers. I know it's not the same thing but I figured it was close Link to comment Share on other sites More sharing options...
Craig N Posted December 4, 2012 Author Share Posted December 4, 2012 What about an upgraded trigger? I like the trigger pull I have on my glock now that's going to donate the frame. I might look at it in the future after I get the rest sorted out. Link to comment Share on other sites More sharing options...

shovel_doctor Posted December 5, 2012 Share Posted December 5, 2012 I would go with a g17 not a 34. I have a 35 open gun and a 17, the 17 seems to handle a lot better. I would go with the sjc magwell before the dawson, the mouth is bigger making for easier reloads. I would also get a frame mounted red dot. I have never shot a red dot mounted on the slide but I would think with the slide moving it would make follow up shots a little more difficult. I would also get a full sized c more, I have the sts on my 35 with a sjc mount, I like the dot and mount but on my 17 I have the sjc sideways mount with the full sized c more. If I could sell my sts and mount I would probably do so to swap over to the side ways mount on my 35. Look at the sjc parts, I really like their products. The mag release imo is a must have. The taylor mag extensions are also a must have, I can get 28 in mine! Link to comment Share on other sites More sharing options...
eric nielsen Posted December 5, 2012 Share Posted December 5, 2012 Agree with the advice to try an Open Glock before you build one. With patience you can find a used, competitive STI or SV or Caspian open gun that costs the same or less. Designed my own open G17 a few years back, LOVED shooting drills and doing dry-fire practice at home with it; liked it not so much at matches. At that time John (now at SJC) advised to not use a G34 slide as his had some cracks form where Glock lightens the slide internally to match the weight of the G17 slide. Something to think about is that in Production (minor scoring, lots of mag changes, basic guns) you have a lot of time to make a good trigger press, over & over, every shot of the match. In Limited you have less time to make good trigger presses, versus your fellow Ltd competitors. In Open you have next-to-no time to make good trigger presses, compared to your Open competitors. So ask yourself (and be aware when shooting practice & matches) - How fast/accurate can you crank out shots with your Glock? Link to comment Share on other sites More sharing options...
Noximus03 Posted December 5, 2012 Share Posted December 5, 2012 Agree to try before you buy. Also, one more thing to keep in mind is your comp selection and how your planned load will work in a comp that big. Link to comment Share on other sites More sharing options...

I'm just going off what people on here have said that the 11 port is the one to get. Link to comment Share on other sites More sharing options...
Noximus03 Posted December 5, 2012 Share Posted December 5, 2012 I understand that. That's how I got started too was by asking questions. Just trying to point out a few things I've learned along the way that no one brought up when I posted something similar. No matter what you go with, test, practice, and have fun.

mitchiepinoy Posted December 6, 2012 Share Posted December 6, 2012 I have a glock 17 slide gen 3 you can trade your glock 34 slide if you want... Glock 34 slide is heavy. Pm me if you are interested Link to comment Share on other sites More sharing options...
fuentesd99 Posted December 6, 2012 Share Posted December 6, 2012 I have 1 question. Why are you going to buy 4 TF +8's? IMHO all you really need is 1 maybe 2 of those and just get a couple of the +5's. You really don't need 4 170mm mags on your belt. 1 170mm and 2 or 3 140mm mags is all you really need. Just my 2 cents. Link to comment Share on other sites More sharing options...

X2 I only have one 170mm mag and only use it when there is advantage to doing so. I have 4 140mm mags, three on the belt and usually start the stage with the fourth one, but three would be just fine.

Mack1207 Posted February 8, 2013 Share Posted February 8, 2013 OP whats the update on this? How did it turn out; what did you decide to change? I'm very curious to see the semi/finished product! Sounds like a good project! Link to comment Share on other sites More sharing options...
EkuJustice Posted February 8, 2013 Share Posted February 8, 2013 I have 2 big sticks and 3 140s for both my sti and glock. It is much easier to load to the 140 than the big stick. I have loaded to the big stick a couple times where i wanted to load after a few shots and go. Link to comment Share on other sites More sharing options...
Parallax3D Posted February 8, 2013 Share Posted February 8, 2013 I ran an Open Glock in .40 S&W for 7 months when I first started shooting open, and I made "B" with it in that ammount of time. Obviously running major 9 in a Glock isn't THAT bad, or KC Escubio wouldn't be using one. Link to comment Share on other sites More sharing options...
Rick88 Posted February 9, 2013 Share Posted February 9, 2013 You should shoot one before you invest much money or time into one. They are NOTHING like the STI based 9's and 38's. NOTHING. This is true, however I as well as others can shoot a 9 major custom Glock just as fast as a custom 2011. The game has changed with the advancement of the Glock trigger it is what it is :-) Link to comment Share on other sites More sharing options...
BoyGlock Posted February 9, 2013 Share Posted February 9, 2013 I played IPSC Open w/ a Glock 17 open gun for 1 yr. While I trained myself to run it as best as I could, the big downside to my experience were the reddots. I formed an ipinion that w/ contineous pounding of maj. 9, the platform itself can handle the load, but the dot wouldnt last. And some after market parts too. I tried a lot of different reddots but my longest roundcount is about 3k for a dot. I dunno if this were also true w/ 2011s. My biggest + is its light weight, rugged, reliable, cheap to maintain (if not for the dot) and not very dependent on pro gunsmiths' work. Link to comment Share on other sites More sharing options...
Xdmeister Posted February 11, 2013 Share Posted February 11, 2013 I would go with an sjc mount for the optic because mounting the optic on the slide can bang up the scope and i would use the cmore slide ride as i find the sts has a window that is really small and finding the dot is quite difficult.

Henry625 Posted February 16, 2013 Share Posted February 16, 2013 The previous post about the Glock being a different feel than a STI in 9 Major is correct. I have an Open Glock 17, at major P/F it is a definite POP to the hand. STI's seem to transfer the recoil significantly better. I have a Carver comp on mine and it works OK, still not as flat as a STI 2011 type pistol. I have loaded Major P/F, but stopped due to my groups spreading wide. As long as I shoot under Major, my Glock will hold tight groups. Mine has a Lone Wolf barrel, Carver comp, and the stock trigger bar but I have the titanium striker, spring kit with 3-1/2 connector. All components have been polished. Trigger pull is just under three pounds and 100% reliable with Winchester primers. Link to comment Share on other sites More sharing options...
Rick88 Posted February 17, 2013 Share Posted February 17, 2013 If you feel a pop to the hand and your group opens up at major your out of spec somewhere. It could be your barrel comp combination or your load. Link to comment Share on other sites More sharing options...
Tuflehundon Posted February 18, 2013 Share Posted February 18, 2013 (edited) I haven't built my Open gun yet, so I can't commnet on a lot of the stuff you have listed, but I have an extended Mag release on my current Limited Glock and have tried the ones with the buttons. I originally put a Zev extended mag release on mine, and I loved it for normal shooting. Then I did a couple of stages were you were forced to shoot off hand. It dug into the webing of my left hand, bad enough that I was bleeding a little at one point. I tried rounding off the edges with a file, tried reshaping it, but nothing solved the issue. Now I use a Glock factory extended mag release and no longer have the issue. With a little practice, it's just as fast and easy to find with my finger as the Zev one was. Not everyone will have this issue, but I am not the only one I have heard with this issue. You may want to try one left handed before you buy.
