Just got off the phone after a positive conversation with Travis at Crimson Trace. Their per/model RD costs run from 150K up to 7 figures, depending on many circumstances. Some of these, like slide release, ejection port and trigger safety placement, would of course not be applicable to the Pup, but as stated in above posts there are other concerns that can certainly affect the final design. I mentioned to him that both the R9 and 380 currently use interchangeable grips, but don't yet know if the hoped-for R45 will or not.
In short, he inferred that if CT gets somewhere in the vicinity of 3500 or more requests for Pup laser grips (on the link also posted above in this thread) they will take the collective interest very seriously, and production in the not-too-distant future could become a reality. If all Pup owners who read this take the thirty seconds to ping them I bet we could get these guys to light us up. IMHO this would be a very cool option/upgrade to the pup, even though I've already modified my stealth with night sights. I would buy CT laser grips in a heartbeat, nonetheless.
I ask you, how cool would it be to laser up your Pup?
