I am a new member to the forum and I just bought a STI Spartan in 45acp and am looking to buy a 22 conversion kit for it. The one offered by STI is over $450 and it is the same KIT offered by Marvin. I am looking at the Advantage Arms 1911 Target KIT but want to get the opinion if someone had used this kit on a STI Spartan and how reliable it is.
Thanks for the help.
