Kahr PM 9 MM Second time at the Range

[Sgt. Stiglitz]

Took the Kahr PM 9 MM to the range today again to try out some different 9 MM Loads I have at home as well as some reloads.

I chrono'd some Hirtenberger 9mm 100 gr Truncated Soft Ponts, Federal 115Gr JHP's, Federal Premium Hydra-Shock 124 Gr JHP's and some Winchester Ranger SXT 127Gr +P+ JHP's. Below are some photos of the groups at 10 yards and chrono data. The Ranger +P+ felt the hottest and gave a good jolt. You know you were shooting something but it was controllable non the less.

GOOD STUFF;
We should have a sticky for ballistic results for each gun...

lead bullits

Hi, Were ( are ) the lead bullits a bitch to clean from that polygon barrel ? Just wondering as I saw lots of posts about not using lead in the PM9 barrel and wondered what the difference would be....WVleo

Those Ranger +p+ are great. A detective friend gave me a box. I also had a box of Federal +p+ that I bought. Much to my surprise, the Feds were quite a bit hotter. They almost sounded like someone touching off a .357 at an indoor range. I don't have any way to check the fps.

Check your math. Did you read the chrono results posted by the OP????
Perhaps 5% faster (50 fps) from a 10% lighter bullet does not equate to "quite a bit hotter"...
