CocoBolo Posted April 28, 2011 Share Posted April 28, 2011 The comp on the left is a really good comp for 38 super type guns. The comp ive found that works the best with 9mm is the Jim hand Egw comp,next is the CNC 4 port comp number 11830. The comp I use on my super is the Caspian "X" Comp, I run about 170 P.F, If you all keep your P.F. up around 170 your 9mm open guns work good there. Jim/Pa Sailors Jim I had my eye on that Jim Hand Egw comp and I thought it could be a good one, the only thing that turned me off was it is heavy. Then again a aluminum guide rod could offset the weight enough to balance the gun out. Funny thing is I like a heavy limited gun and a light weight open gun.

CocoBolo Posted April 28, 2011 Share Posted April 28, 2011 Yes, after reading all the stuff on comps. Just screw one on and shoot, shoot , shoot It reallt doesnt matter the design. Nuf said. No doubt you can work around a bad comp but been there done that, and yes it makes the difference between a violent gun and one that you can shoot fast and comfortable. A lot can be done with the right powder, in a 38S but with a 9 there are fewer options. Jim Anglin builds some of the best shooting and running 9 majors I've seen, if he says the Jim Hand is the way to go, get one. Link to comment Share on other sites More sharing options...
Bret Heidkamp Posted April 30, 2011 Share Posted April 30, 2011 Comps make a big difference in their design, but mostly I prefer forward angle or straight up and 4 big ports. The Dawson #2 is about the best I've ever used, and I've used just about all of them. 3 ports don't work well unless it's a steel gun shooting minor. I would not "just screw one on and go shoot" - you have to figure out what works, for your style of shooting. Spring weights are just as critical, you can't just "go shoot" there either. Open guns are very sensitive to minor changes, and you need to experiment with what works the best with your powder / bullet combo. For instance, I personally prefer 115's and lots of powder vs. 124's. I like a flat shooting pistol, not a flippy one. Anyone here that has seen me shoot, I shoot fairly fast, most splits are 12's and transitions can be 15's on close targets. so for the OP of the thread, yes angles make a difference but it is small in my opinion compared to the number and size of the ports. 4 port, straight up, dawson #2 and work on springs, recoil rods, and powder loads for around 169 pf. But of course YMMV and it's all about what you like, not me. I'm just saying experiment and you'll narrow it down. You can adjust to anything, but don't handicap yourself with equipment - be true to your own style. my favorite open setup: dawson 2 comp sprinco open race rod 9# spring 15# hammer spring shortened slide 3/8 to 1/2, some flat topped, some not, doesn't matter scoop cut the back where the bomar would go standard bbl let it rip - this setup is not for the timid.

Bret Heidkamp Posted May 1, 2011 Share Posted May 1, 2011 forgot to add that I also port the bbl twice, 12 o'clock, once in the comp thread area, once more behind that through the slide/bbl. No the comp doesn't come off when it gets hot, just in case you're wondering! :-) Use loctite 620 retaining compound on the threads, the green goo of doom.

CocoBolo Posted May 1, 2011 Share Posted May 1, 2011 Saw an interesting Comp Saturday in a 2 gun match, the gun had a hybrid barrel 4 holes and the comp ports were split out the sides of the comp. The gun seemed to shoot pretty well. I asked about the load he was using and he said it took a while to sort it out but the gun ran well at 190pf. Yes, at 190 pf he reached the taming of the interesting comp. Sure glad I not running a rig like that. Among GOOD comps there might not be a whale of a difference but some flat suck.

jjanglin Posted May 1, 2011 Share Posted May 1, 2011 The Jim Hand comp from Egw isnt that much heavier by the time you get it all matched up to the slide it is just fine, I dont think that aluminum guide rod is a way tolighten a gun, because the aluminun is so flexable it can slow a slide down a bit and make it feel like it is sorta bouncing so it seems to me. I too have a barrel set up that I run 190 P.F., it shoots flat and makes the RO's a little jumpy , then again if I feel like making a lot of noise I can shoot the 9x25 set-up I have I think the open gun I have Caspian 38 super is as good as it gets, I use one of their "X" comps it sure works good for me. Idont believe in changing guns often, my 40 Limited Caspian is ~ 13 years old.Its the older style frame, my opengun is the first year square trigger guard model dont know howold its is got lots of round through it. Get something built you like maintain it good and just shoot it, soon it will be an old friend and you will like it a lot. Jim/Pa Sailors Link to comment Share on other sites More sharing options...
1911Prof Posted September 4, 2011 Share Posted September 4, 2011 Has anyone had any experience with EGW's 8-port 6-chamber Compensator? It looks like it would be long and nose heavy, but might help settle my gun down. Link to comment Share on other sites More sharing options...
GlennRasch Posted September 4, 2011 Share Posted September 4, 2011 Here are some pics. of the new comp I just machined ... tested it of last week, and seamed to work fine. I'm going to close off the end port with a clamp and see if that make's any difference. NO side holes... Link to comment Share on other sites More sharing options...
shred Posted September 4, 2011 Share Posted September 4, 2011 If you ever want to know if a port is doing anything on a comp with a particular load, go to the range with a roll of electrical tape. Wrap a 2-3 wraps around the port in question and fire a shot. If it doesn't cut the tape, that port isn't doing anything useful. The more wraps it breaks, the more gas is being redirected.

Be sure to pick up the shards of tape. It works best with stretchy electrical tape since you can look at the residual pieces and see how hard they were stretched before they broke. Masking/Target tape is not nearly as useful. Link to comment Share on other sites More sharing options...

I tried this today at the range......... I found that the front port worked just fine. The gun shot super flat with the 4 port's, NO side port's will be added.

cworks Posted September 19, 2011 Share Posted September 19, 2011 Tried the tape method the other day and my 5th port is defiantly pushing gas through it. Cut the tape every time. I have a 3 port Schuemann barrel and a 5 port comp. No side ports. Link to comment Share on other sites More sharing options...
2alpha Posted September 19, 2011 Share Posted September 19, 2011 My 2 cents. If you have a decent comp, any of them in common use today, you will get more gains playing with your bullet,powder, and springs than changing comps. There is really nothing that new under the sun with comps that I've seen. IF you never practice enough with any given setup you never get in tune with it and never see the potential. Too many seem to want something magic to improve their scores when good practice and some good instruction is where it's at for everyone. If you have a reliable pistol and block out all those thoughts of better comps or whatever, apply yourself, put in work on the things you don't do well you will see results.

tunakilla Posted September 21, 2011 Share Posted September 21, 2011 (edited) Several years ago I had a chance to shoot one of the TOP Shooters (then and now) open gun. Quite frankly His gun was the most violent hard to shoot guns I have ever shot, my equipment is/was MUCH better. After that lesson I just worked on my shooting, best thing I ever did.... He IS a top shooter and it is not How Flat or Soft the gun is.......Spend the time looking to improve your shooting ability........
