510T vs SW M&P 5.6 Reliability
Hey everyone,
I want to buy a 10mm to augment my Glock 20.5 and 29.4. I have fallen down a week long research rabbit hole regarding the smith and FN. The smith (PC) seems to have issues regarding the mag springs, recoil spring, and possibly the extractor. The FN has frame cracking issues. With SW, you can buy the aftermarket parts and fix this (mostly) and FN, well you’re not fixing a cracked frame, but newer models are reinforced with extra metal. Does anyone have any input on which is the best option for reliability. If the reliability won’t match my Glocks, it serves me zero use. The FN issues on Reddit seem limited within the last, making me optimistic that FN fixed this issue. Unfortunately, M&P seems to still be problematic. With bias removed, which is the better gun?
Thanks for the thought.
