Bought a Viridian C5 green laser the other day for the 30SF and plan to use it on the G21 also. LUV the thing. It is a boon for my aging eyesight. Can see in daytime and at night, WOW! I should have really done some homework on holsters though!! The TacLoc that Viridian sells does not fit either the 21 or the 30. The other thing is , I'm left handed!! They have a left hand model for but they do not fit either weapon. Have spent half the weekend Googling and going to almost every holster mfg. with no luck. Anyone know of some maker who has a holster for a glock 30SF with a Viridian Attached? It is my EDC in the warmer months and the 21 I use in the colder weather. I realize I could probably get someone to make a custom holster but I'm on S.S. pension and cannot afford that type of luxury. Really sucks having a weapon that is now ideal for me, but can't find anything to carry it in. I know all the naysayers about lasers etc., but this is a great tool for me and my situation, and if that works, then it only makes me more proficient and confident. That's a good thing.
