S-PRO is our next-level pistol conversion kit, featuring a spring-loaded stabilizer (which can be converted to a buttstock by removing the included brace attachment), MLOK mounting options, and broad compatibility. S-Pro is compatible with Glock, Canik & Walther PDP. We will soon be adding support for the SIG X Macro with more to follow. The unit is designed to be modular, and using it with another compatible gun will only require swapping a small adapter piece, which will be sold separately.
