Um...... I put skateboard tape on mine. I don't know of anyone making barrels for the P95. I'm sure someone makes night-sites for it, and a quick search on the net will reveal many holsters available for it. Also, full (15 rds) and high cap (20 & 30 rds) mags are widely available. Good luck!
Hmmmmm, let's see now. Standard capacity magazines are a must. The only other thing I have done to mine is added a Hogue Handall. Yeah, you have your skateboard tape fanatics, but those finger holds are great!!!! Other than that,I would add nothing. The P95 is a great out of the box weapon.
You should be able to get Meprolight night sights on your 95...I have them on my 97 and they are great!!Almost a must for a home defense weapon.12 year gaurantee too.I did have to pay $25 to have them put on since the front sight needed drilling....no biggie,it was worth it...you will like them!!
