Have question about mounting laser sight on a GP100.

Is it realistic to use this model left handed without any modification?

If that won't work, any lefties recommend something?

Shouldn't be a problem, the middle finger of the gripping hand is what turns the laser on. Sight it in left handed and you should be fine. The laser portion is above your grip.

They work great.
One think to keep in mind is green lasers are easier to see in sunlight.

OK, thanks for the info.

Just my 2 cents. I have one, I bought years ago and have had nothing but good luck. I would buy this product again...I'm very happy with it

Maybe I should have been more specific. I put it on a super Redhawk Alaskan in 44 mag. I know many people might question that, but I have that gun in the middle of the house where I can get at it quickly from any direction. I wasn't really using the gun so I made it into a home defense weapon. It's a quick point and shoot. A nice little surprise for any home intruder......wink wink. PS....as usual, I take everything too far and even installed full size wood inserts from the normal Lett gp100 grips
