Yoseppy Posted March 4, 2022 Share Posted March 4, 2022 I’m looking at ordering my first open gun, and was wondering about poppleholes. What are the pros and cons? I tried to find some information on here about them but wasn’t getting very far. Link to comment Share on other sites More sharing options...

Don_B Posted March 4, 2022 Share Posted March 4, 2022 Barrel ports will make the pistol loader but will also make it snappier and quicker back on target. Some people like it, some don't. My suggestion is to try pistols with and without ports to see how you like it. Link to comment Share on other sites More sharing options...

MikeBurgess Posted March 4, 2022 Share Posted March 4, 2022 (edited) I haven't done apples to apples comparisons with identical guns but I have shot and built guns with and without holes, what I can say is they feel different, not really better or worse just different. As a very generalized statement I would say the ones with holes tend to be snappier and without softer, there is probably a slight difference in how flat they are but as long as the springs are set up correctly so the dot returns to where it left from I really don't notice. That said you can probably make a bigger difference in feel by changing recoil spring, main spring and firing pin stop shape combinations. the last several guns I have built have had 2 barrel holes because that is the current fashion rather than for any performance gain I can point to.

Posvar Posted March 16, 2022 Share Posted March 16, 2022 A well known builder is now using 4 popple holes in 9mm and I wonder just how much powder is needed to make PF. I like two but that is just me Link to comment Share on other sites More sharing options...
cperazza Posted March 30, 2022 Share Posted March 30, 2022 (edited) What I have seen is - 9 Maj 2-3 popple holes (norm 2) - 38SC 3-4 popple holes (norm 4) They help keep the gun flat, but there is additional tuning you might have to do depending on your grip, shooting style, loads (USPSA or steel challenge... - recoil spring 7-8lbs... 8V - mainspring 17-19lbs... 17lbs - magwell aluminum or stainless (Added) "Current available" Honchos don't have popple holes and they shoot fine. Agree with previous comments, see what you can get a hold of to try to help you make the decision that is best for you.

Posvar Posted March 30, 2022 Share Posted March 30, 2022 Regarding the Honcho, mine had no holes and shot really well but was also super front heavy so maybe that affected it. My favorite feel for 9mm major is the new offset angled hybrid holes by SV. Keeps the gun super stable and a quick up and down then return to zero very fast.

zzt Posted March 30, 2022 Share Posted March 30, 2022 On each of my three Open guns I went with a straight comp first. None shot as flat as I wanted so I added poppels. Two 3/16" dia. in a v2 config on two of them and three 5/16" vertical in the last. So what happens when you add poppels? You rob gas from the comp. Yes, the gun shoots flatter, but hits the hand harder. You lose velocity. You make up for that by adding more powder. That's a good thing, because there is more gas to 'work' the comp. So, bottom line: if you want the softest shooting gun, go with a good comp and as much slow powder as you safely can fit under a 115gr JHP. As you go up in powder charge you will get softer and softer right up until you start to get excess gas jetting out the front of the comp. If that is not flat enough for you, add poppels. In 9mm major it is impossible to fit enough slow powder in the case to shoot flat AND soft. So you have to choose one or the other, or a little of both. BTW, the well known builder using four poppels in 9mm is using 1/8" dia. poppels. You don't have to struggle to make PF. Link to comment Share on other sites More sharing options...

Mine were not 1/8" and even with "just" three it was not easy with N340/350 as recommended by the builder. Link to comment Share on other sites More sharing options...

If I could fit more of a slower powder in the case, I'd be using that. Even getting silly with PF, I cannot generate enough gas to fully work the comp.

I have since started to use 3N37 for 9mm major as recommended by current builder/manufacturer. Zero issue making PF with N350/3N37 and it shoots so nice.

tator2k Posted March 31, 2022 Share Posted March 31, 2022 3N37 and 3N38 have worked best in my hybrid (comp and 4 ports) 38SC, you need a lot of gas! But it's loud! To the point, ROs that know me ask what gun I'm running and will hand the timer off to someone else. I'm currently trying to figure out if I can rebarrel it to 9mm comp only.

However, you may have to change your powder. I literally cannot fit enough 3N38 in a 9mm case to make major with a 115 JHP. With a 124 I can (barely) but have to seat and crimp in the same operation. Otherwise the OAL will 'grow". Switching to AA7 will cure all that. Link to comment Share on other sites More sharing options...

What I hate about 3N38 and 9mm major is the mess that happens with the press. Link to comment Share on other sites More sharing options...
