Review: JK Armament 155 RPX 9mm Suppressor

If they actually achieved those dblevels I’d give in and get one. To date, except for one on a .22, I’ve never seen a truly “quiet” pistol. I know there are some out there supposedly, but I’ve been on the firing line with a meter when a variety of different suppressed weapons were fired and thus far the only sub 100 db I’ve seen was on a ruler 10/22 with a big can

I have a few that are really quiet, i don't know nothing about and DB ratings but one ruger precision you can only hear the firing pin hit. now this is using sub sonic ammo too. even with regular ammo it's really quiet. using a dead air mask. Different ammo has a lot to do with it too. i also have some 9mm that are really quiet. also i have noticed different guns are quieter than others using same ammo and suppressor. blowback will make some sound, some allow more than others.
But far as suppressing 5.56 and up, no they are not whisper quiet but they are noticeably reduced sound and Some AR's are quieter than others. The more slack between the halves the more blowback and sound.

Thank you! It's very hard to find reviews on the RPX and even the older PCX models. Based on the very limited reviews I can find they seem to perform pretty well, maybe not the best/top tier performance, but since they are adjustable with different baffles and end caps you can tune it to your needs.
The RPX 45 is intriguing if it can be do-it-all can with a few different end caps. That way 9mm, 10mm, 45mm, 556, 30/308, etc. are all covered. It can potentially be used for pistol for home defense when stored away and then rifle when out hunting/training.

Glad you enjoyed it and it was helpful! You raise a good point about multi-cal cans, and I have benefitted from them too across platforms.

Appreciate the review, but those Db readings really don't tell any story. With the unsuppressed numbers all under 100Db and most under 90 Db, the recordings weren't anywhere near accurate. And the reduction numbers are unimpressive if anywhere near accurate. They're only showing between 5 & 15 Db reduction. That's not much at all. The suppressor could be much better than these results show, but there's really no way to tell from this article.
I have a number of suppressors. Two of them are modular. I've found I really don't use the modular function much, if at all anymore. I played with it at first but wound up leaving them all at full length. I know it sounds cool to be able to scale the suppressor down, but in reality, I wanted full suppression. And multi caliber suppressors can save you some money, but once I got into the NFA game, I wanted to have dedicated cans for each host. It's kind of a pain to switch out mounts for each host. Some people may like to use one can for multiple hosts, I just found it a PITA. Just my opinion...
