Hi,davewms said:Does anyone own a Beretta 950, 950B, 950BS, Jetfire that they can compare to the P3AT?...
...I have a 25 cal. 950B Jetfire that carries well, but it's way underpowered. (You can't always stick it in the BG's eye!!)
Brassfetcher has some good gel test results at his website comparing the Beretta 21 A against the P3AT which I think is as close as you will get for a true comparison.

The 25 ACP with FMJ has a penetration of 15"+ vs. about 21" for the 380 Auto w/FMJ against bare gelatin, what does this tell me? The 25 ACP has adequate penetration with FMJ but requires very good shot placement. The Beretta 950 also has 8+1 shots vs. the P3AT's 6+1 shots giving it nominally 29% more firepower.
There's a small arguement for the Beretta 950 vs. the P3AT using FMJ since it has adequate penetration and greater firepower if you are an expert shot. That arguement goes out the window with expanding bullets, or you are less than a great shooter (big majority of people under stress.) I think evidence from shootings with both cartridges show that FMJ is ineffective in both, but the edge goes to the 380 Auto using FMJ. I hope the info helps.
