I recently purchased a SigPro SP2022 from Academy Sports for $499.99 (never found a Sig for around $500 before). Bought it almost sight unseen. I haven't taken her to the range yet, but I have disassembled, cleaned and oiled it (as per the Sig website). I have noticed that the feed ramp seems to not like to feed the 147 grain Hornady TAP that I currently have in it (all that Academy had for SD ammo). The feed ramp now has a layer of copper on it. However, when cycled, the ammo does feed properly. Also, when I cycle ammo through it, the magazine seems to wiggle...is that supposed to happen? Anyone else have a SigPro SP2022 and can comment on how they like it?
