The king of sight pushers - MGW Armory Sight-Pro Compact Sight Tool

This is mother of all out there. It holds slides in solid. Pushes easily and straight. Works on standard and suppressor height sights. I wish I had bought this first and once instead of trying to use a cheaper brand that ruined a rear sight on a 320. If you do a lot of handgun sight swaps, this will pay for itself in no time. The MGW specific for the Glocks is just as solid and much cheaper. The only downfall to this is needing to buy shoes for specific models but that’s part of the game. The shoes are gun model specific so you are not using a universal product that can potentially mar up your slide or damage your new set of sights. If you start with the shoe you need most and buy as you go, it’s not that bad. I had friends buy the shoes and I swapped their sights for the shoes. Locally, if you can find a shop that will swap them, even if you bought the sights from them was 45-60 bucks. A pair of shoes 15-25 usually on sale everywhere so win win.
