No factory packaging but were as new and not previously loaded. Great value and quickly delivered.On Tippmann Arms M4-22 .22LR Magazine - 25 RD (Open Box)JJustaguyVerified Reviewer4.0 star rating03/31/25Gret Grip but could use improvement.Review by Justaguy on 31 Mar 2025 review stating Gret Grip but could use improvement.This is how many compact grips should be made but with a few changes. 1- It needs a double undercut to really allow a more comfortable grip. 2) A new grip texture could be used. I put goon tape on mine and makes it a lot nicer feel. But the main reason I bought this grip is to get the larger hand area and not have that ring/pinky finger area asking what now. ? Yet being able to keep the same holsters is really great.On Tyrant Designs P365 Snub Nose Grip Module w/ Safety CutoutAAb007Verified Buyer5.0 star rating03/31/25Lefty here - perfect purchaseReview by Ab007 on 31 Mar 2025 review stating Lefty here - perfect purchaseAs a lefty I can’t work a gen 3 Glock with index finger. This fixes that - takes a bit of re-learning thumb placement - almost need to hook around to clip the most forward part. Soon as you get that it’s easy!On Rainier Arms MARS (Magazine Advanced Release System) for Glock Gen 1-3RRichard B.Verified Reviewer5.0 star rating03/30/25EVEN BETTER!Review by Richard B. on 30 Mar 2025 review stating EVEN BETTER!The backstrap is awesome but adding this magwell just turns it up to 11! The backstrap and magwell should be sold as a combo. I dig how the magwell really sits super tight and the attachment point is beyond rock solid. Mag reloads are smooth and intuitive with how well thoughtout the design is and the overall look is just killer with a great finish.On Mischief Machine P365 X-Macro MagwellRRichard B.Verified Reviewer5.0 star rating03/30/25Absolutely awesome!!!Review by Richard B. on 30 Mar 2025 review stating Absolutely awesome!!!This backstrap really fills the hand and has killer texturing and great ergonomics.
