Which is more reliable? Both have been around for years and probably will be around for more years.
The Hi-Point handguns use the physics of more energy needed to move mass. The PPK uses springs (recoil and main). The 1911 (and others) use a lint to keep slide and barrel together until pressures decreases. Others use a camming system.
Comparing two different .380s (one a PPK/s, the other is a Kel-Tec P3AT), I have found that, for me, the PPK/s is more accurate.
Comparing my H&K PSP P7 (blowback) to a clone of the Browning Hi-Power, they both are reliable. And depending on ammo, the accuracy is not much different (I did some work on the BHP clone before this).
I would not worry about which is more reliable in making your decision. If the firearm was not reliable, it would not stay on market too long (except the dern Jimenez/Jennings pistol).
I guess so. Still I like to educate myself on the mechanics of things. I've taken them apart and put back together but even then it's not like I'm re or reverse engineering something, so it's nice to get an understanding of how and why things I'm interested in work the way they do...
I did reference the user manual on these and it said this:
Ribs on top of barrel engaging recesses in ceiling of slide when breech block face of slide strikes barrel on its forward movement and pushes it ahead and up on its oval shaped pivoting hole in barrel lug.
Going to decipher what that all means later! Lol haven't even eaten breakfast yet and this is already too much to digest! Lol
Thanks again man!
