Today I tried the plunk test using a friend's X-Treme 147 RN's, OAL 1.147". They went right in my G-19.5, then slipped right out. Good to know that will work for me. Even though I load my X-Treme 135 HP's to 1.135", to me, they just "look" too long (attached photo). To fit, I'd have to shorten by 0.040". Your thoughts? I called Berry's today asking what bullet profile might work in my Gen 5. Jason wasn't familiar with with the Gen 5, but told me many of their sponsored competition shooters run their 124 HBFP and HBRN. I don't know if that was for USPSA or IDPA. Most IDPA guys around here tend to run 147 RN because they say it gives them less felt recoil. If that is the case I wonder why the sponsored shooters run those 124's?

Thanks for your thoughts guys. Good info. I've been reloading about 18 months and have only developed loads for 147 RN's and 135 HP's, so I'm far from an expert at this stuff. However I do know to start low and work my way up. When I developed the 135 HP load, a OAL 1.105" didn't seem to be as accurate as 1.135". That's why I'd like to stay with a longer OAL. The shorter OAL might not make a difference in the Gen 5 with its "Match" barrel,, but I still have 4 Gen 4's to shoot, so I'm trying to find a happy medium. Rather than shorten the 135 HP all the way to 1.095", I'm going to try the 147 RN. If that still doesn't suit me, I'll take your suggestion and try some 124 RN's.

I shot my Glock 19 Gen 5 for the first time today. No issues with factory ammo, but the handholds I’ve been using in my Gen 4’s wouldn’t pass the plunk test. The handholds are X-Treme 135gr HP’s, .356’dia, OAL 1.135”, using 3.7gr of VihtaVuori 320. I don’t remember the speed, but PF is about 132-135 through my G34. To pass the plunk test I had to reduce OAL to 1.095”. Next I’ll have to determine if there is room below the bullet for the powder. At best it’ll be pretty tight in there. Am I getting into dangerous territory? Should I change bullets? If so I’d like to stick with X-Treme plated. Any thoughts? My last question is, will such a short OAL effect accuracy when shot through my Gen 4 Glock’s? I just thought of another last question. Are there any questions I’m missing, because I don’t know what I don’t know.
