Notice the difference in OAL between the Prvi and the Winchester flat points.
A Winchester in the magazine.
A Prvi in the magazine. The lower rounds are Winchester flat points.
The Prvi shoots fine out of the Seecamp, you just can't fit more than one in the mag. I spared you the picture of the 500 rounds of Prvi that I bought for practice. Shooting one at a time, the 500 rounds should last me a century or two.
