Its not hard if you have some mechanical ability. A vice, punches and a ball peen hammer are minimum on tools. Since you want the Meps instead of pounding them in use a file and fit them to the pistol. If this sounds like too much then... Any sight that is purchased through me comes with free installation and less than a 24hr turnaround time also return shipping of the lside is taken care of. All I would need is your slide and you can get it to me for 5.00. If you already have sights or you just bought the sights somewhere eles 15 buck will get you an install return shipping included.
