Well I really love my setup. I own a 2001 V1 which has been upgraded to the newest V1 software. My M-25 has saved me I don't know how many times!! and the veil stealth coating is great too. As for the others such as LPP or laser interceptor, I can't say. I do know that Blinder has the best customer service over them all. If you ever need a hard question answered, Leon and Bonnie will help you. I currently own a Pro laser II gun and have tested my M-25 and my friends M-20. Both Jam very well at all distances.. The weather has never bothered any of my toys.
I will say this, laser is becoming the choice of most county cops in my area. I hope that helped a little.
