I prefer the Ameriglo Spartan Night Sights.

Green rear with green front inside an orange outline. Really helps pick up the front sight during daylight. I put these on all my Glocks.

Often I just replace the front sight and leave the rear without any tritium. No one takes the time to line stuff up. Put the front sight on the perp and squeeze. I really like the orange front/tritium combo. I am a Glock certified armorer which is the equivalent of having a kindergarten diploma, but I have changed out dozens and dozens of sights for folks and I always recommend these. No complaints either.

Stupid easy. You need a single tool.

Put some red loctite on the replacement and make sure it is straight. Leave it alone overnight to dry. Just the smallest bit of red loctite on the threads. Also make sure it is square after installation.

This is the best tool available and much superior to the Glock tool.

Yes. I have the sight pushers. Local guns stores that sell Glocks have them usually. Call around. Expect to pay $25.
