I picked up my new Compact 2.0 9MM today. I'm in California so it's been in DROS prison for 10 days. I'm 72, into firearms since 10 yrs old. I'm pretty familiar with the platform given I bought a Shield when they first came out. The Shield is a great pistol. Back to the Compact while looking thru the box and the goodies that come in it I came across two slip-on mag extensions(they look like X grip). The mags that came with it won't work with them....they won't latch so I'm assuming those are meant to be used if you're using mags for a full size 2.0 in your Compact, right? Also while browsing the owners manual it shows pulling the backstrap/palm swell off as part of the field strip disassembly. I can't tell for sure if that needs to be done to get the slide off or if that's about getting access to the backstrap takedown tool to use to push down the little lever in the magwell. Does the backstrap/palmswell need to come off to field strip the Compact or not?
