Cheflife15 455 Posted January 5, 2021 I purchased 4 boxes of Prvi Partizan 9mm Luger Subsonic Ammo 158. Will there be any issues shooting this through my guns? Cz sp01, cz shadow, walther ppq q5? Quote Share this post Link to post Share on other sites
GRIZ 3,369 Posted January 5, 2021 There should be no problems with pressure or functioning in your Walther. The only surefire way to find out is to shoot some. Quote Share this post Link to post Share on other sites
Krdshrk 3,877 Posted January 5, 2021 Technically 147gr 9mm is usually subsonic out of a 5" or shorter barrel. 1 Quote Share this post Link to post Share on other sites

Every subsonic I tested through the about 9" barrel of a MP5 or PCC stayed subsonic through a chronograph. Most PCCs lost some velocity compared to firing through a pistol. My guess is the powder is consumed and barrel friction comes into play. Quote Share this post Link to post Share on other sites

Golf battery 1,223 Posted January 6, 2021 Meets power factor. I think even for pcc at carbine. If not. Very close at 115 gr. Ouch. Far from pf. Like 20 off Quote Share this post Link to post Share on other sites
