I have an older Gen 1 4095 Carbine with 5 orange follower 10rd mags. 1 mag was giving me stoppages so recently I ordered a new mag from HiPoint. It was shipped from Strassell's Machine Inc and is stamped 10mm/ 40 s&w. I tried the new mag this afternoon and had nothing but problems. The first round loaded fine but when it fired the next round stove piped. I cleared that, recharged the weapon and click, failed to strip round from mag. Recharged and fired that and the next 7 rounds and then another stoppage. The follower in the mad was stuck with 2 rounds loose in the mag body. Dumped the loose rounds out and smacked the mad against the stock and freed the follower. Reloaded the last 2 rounds and click, again failed the strip a round from the mag, recharged and fired the last 2 rounds. My question is, why are they using the same mag for two different calibers when the rounds are different lengths? Is that what is causing the failure to strip of round?
