yeah to say that CT's customer service is excellent is an understatement. They seem to have taken a page from the reloading companies handbook, emulating Dillon, RCBS etc, with amazing service and helpful employees. They often visit various pistol websites and offer up hints and tips to handgun owners, even when it might not be in their best business interest to do so. CT is absolutely one hell of a company.
Now about adjustability with Lasermax guiderods. They do have a couple models (or did last time I looked), that allowed for adjusting, but in all reality it's not needed with the regular ones. The ones that were adjustable were for specific 1911's that could be very very different from one to another. the standard Sig, Beretta, Glock etc are all known to be within 2 inches of POI at 25yds out of any other pistols they are fitted to. Which is more than good enough for combat/self defence shootings. They aren't designed for, nor intended for "precision work". The CT's are adjustable because of their location, being in the grip of the gun allows for all sorts of reasons for them to be "off" with a factory setting.
As well Lasermax units blink, something I like, but others don't, CT units batteries also last longer, not sure why, might be the type and size of the battery, or it could be laser design.
