![]() ![]() But there is not enough market to make a dedicated 9mm frame a viable product (except Korth) so you end up with 9mm in a 357 Mag. ![]() In theory you could create an I-frame that would have the same overall size as a J-frame but with a ~3/8 longer barrel and due to the shorter frame and cylinder a bit less mass and bulk. If they actually made a 9mm length frame similar to the old S&W I-frame then you might have something unique and useful. You have this relatively short cartridge in a unnecessarily long cylinder. They just take their 357 Magnum revolver and chamber the cylinder for 9mm. No manufacture makes a dedicated 9mm sized revolver frame. At least not with current offerings in 9mm revolvers. Unless you are heavily invested in 9mm (ie piled deep and/or reloading it) a 9mm revolver does not make a lot sense. Speer and Buffalo Bore are my favorite ammunition suppliers in any caliber with Buffalo Bore being the most powerful I have tested from any of the major OEMs. I highly prefer Gold Dot bullets and will be getting Speer 135 grains as soon as I can find any for the LCR. 44 Special using Buffalo Bore ammunition. 38 Special +p ammunition from Buffalo Bore or my winter gun of a Taurus. I really miss my awesome Glock G36 but now carry a Ruger LCR/357, 1.8" barrel, using. I do not have Buffalo Bore's ammunition in 9MM but believe it would have similar power factors.Ī couple years ago I switched from auto loaders for CCW to revolvers with all ammunition being flash suppressed, if possible. If I did a gelatin test I believe I would see much greater penetration from the heavier bullet. Very stout ammunition in a small revolver. 38 Special (#20A) 158 grain LSWC HP has a PF of 161. That said, my SP101 with Buffalo Bore (#19G) 125 grain JHP has a PF of 163 and their. Most good ammunition have a PF of 138 - 142 in either of these guns. ![]() Without getting into minutia detail, they are relatively equal in Power Factor, which includes velocity and bullet weight. More to your point with a relative apples to apples comparison using a Kahr PM9, 3" barrel including chamber and a Ruger SP101, 2.25" barrel not including chamber which are functionally very close. All things else being equal with expanding bullets, a lighter faster bullet will penetrate less than a heavier slower bullet since the faster bullet most likely will expand to a greater diameter and penetrate less. However, when speaking of short barrels of any caliber or weapon type (handgun and rifle), the concern is more associated with bullet performance as a result of its design parameters and velocity. I believe ammunition/bullet choice is far more important than caliber. But I have changed my opinion to heavier bullets due to more recent published gelatin tests and better bullet designs. For years I was a fan of the mid weight to lightweight bullets and higher speeds due to kinetic energy. I hand load and test all of my commercial and personal loads through a chronograph. This is a complicated issue and could generate "discussions". ![]()
