I have two P220s and about 10 8rd magazines. I'm thinking about getting ahold of either a P245 or the new P220 Compact as a backup/CCW. My question is, do the P220 8rd magazines work in both the P245 and the P220 Compact? Magazine interchangability is important to me as a backup pistol so that I can draw duty magazines from my pouches to use in my backup pistol. Thanks.
