3" Inch 9mm Carry Loads?

[PA PATRIOT]

With all of the Micro 9mm pistols currently the new fade with CCW owners I was wondering what if any of DocGKR's approved carry/duty loads would offer acceptable performance in a 3" inch barrel.

Now most likely the best choices maybe the Barnes XPB 105 & 115 gr JHP (copper bullet) or Speer 9mm +P Short Barrel loading but I have not seen any data to confirm either as a viable short barrel loading.

I remember in a old thread some talk on the now discontinued Winchester Partition Gold 124 gr JHP (RA91P) being a decent short barrel loading but can't find that thread under a forum search.

HST 147gr or 124gr +P

HST 147gr or 124gr +P

Can I ask what data you are basing your choice on that qualify these loadings acceptable with 3.0 inch barrels?

Thanks!

Basing on ballistics data I have found when researching for my EMP 9mm.

Review Molon's chrono posts on this...basically 147's suffer less velocity loss out of short barrels. Federal sells both standard and +P 147gr HST loads that would be a good option.

147 gr doesn't give me a warm and fuzzy feeling when it comes to 3" barrels. I guess I just haven't seen enough data. It just seems too close to the reliable expansion window velocity wise.

I've seen the Gold Dot SB tested from Glock 26s and Kahr PM9s, it does exactly what you would want it to.

I've had good results with the 147gr HST and Ranger T. If you don't feel comfortable with the 147gr, give the Ranger RA9TA 127gr +P+ a shot.

My 3" gun is a Kahr PM9. I use the same ammunition in it as in my larger 9mm's, which is winchester Ranger T series 147 JHP.

It's been awhile since I studied it. (I've had the Kahr since 2005.) But when I looked into it at the time, the velocity loss from the 147 gr loads by going from a 4" to a 3" barrel wasn't all that much.

I worry more about shot placement with the little guns than I do about losing a few FPS.

OK. Whats the expansion window for 147gr loads?
