I picked up a used warthog in 45ACP today. I really like the gun and how it shoots. My questions are does the kimber or Colt defender recoil spring assembly drop in on these guns and work? Also what parts are 1911 compatible? Last thing is my gun came with only one 10 round magazine. Don't know if it's factory or not. It's stainless steel and flush fitting. It's marked "made in Canada" on the magazine body. The base plate is a Pearce grip extension. My gun is black in finish and marked "Para-Ordnace Inc." "FT. Lauderdale FL." On the frame. And "Para HI-Cap" on the slide. The I've tried google but can only find extended 13 round magazines with grip sieves on them,and I'm wanting another flush fit 10 round magazine. Thanks for any help on this.
