S-PRO is Recover Tactical's 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. 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.
