Smith is saying that one or more chambers are out of spec diameter-wise? That seems very hard to understand with a stainless cylinder, especially when the early 640s were +P+ rated (-I've expressed my theory on that here before) and that the same cylinders in other guns (e.g. the 642) are +P rated.
I'd be interested in hearing BigBoku's thoughts on this as well.
Time to put up the BB signal!  |
This would be a first for me, I also have a 90s vintage No Dash that has been fed nothing but +P Duty Ammo and has no discernible wear on the internal or external components of the weapon.
Over my 20 years at Rodmans Neck I have seen plenty of model 36, 60 and Colt DS revolvers that had timing issues which can be attributed to the +P duty ammunition diet (especially the Colt DS). I also have seen more than my share of 640 revolvers which in my experience are the M1A Tanks of the J Frame line. I have personally shot ALOT of +P ammo through my personal 640 and several of the Department owned 640 revolvers that have been in the armory forever. The Department owned revolvers all have unknown +P round counts and I have never seen anything that would require a cylinder replacement directly related to +P ammunition.
Even with the use of duty ammo for off duty qualification the 100 rounds a year over 20 years would only add up to 2000 rounds which is still below the 3000 rounds of +P ammunition factory rating of post 1972 Colt DS revolvers.
Again, I am hard pressed to attribute the cylinder replacement to excessive use of +P ammunition as there are many other parts that would also be in need of replacement a lot faster then the cylinder.
Just my 2 cents worth, Stay safe!
