I have an unfinished casting of an Arminex Trifire pistol frame I've been sitting on for several years. I found a stripped Arminex slide on gunbroker that I would like to use for completing this firearm. My biggest challenge would be fabricating the firing pin lock that attaches to the slide. Is anyone familiar with these pistols? Are there any other parts other than the FP lock and back strap that are different from the 1911? Many thanks.
