For about ..
3 years now, I've carried a matte finished T45UC on a pretty much every day basis...
I don't shoot it all that much, but just last week...
I noticed that after a lot of carry through our 'Winter' season down here, under flannels mostly untucked, in a kydex IWB holster, the poor little thing was growing dust bunnies, and was overall very much in need of a good cleaning...
But before I did, I decided to burn the rounds that were in it, just to see how it worked in this condition... So I stepped out into my 'backyard', and up to the bank of a channel that flows between the 2 lakes that my property has access to, and fired the first mag, DA first pull, then as fast as I could banged out the rest SA into the water at the edge of the channel.... Then put the 2nd mag into it, released the slide, and repeated the second mag that I carry as a backup.
No FT anythings! After this 'test' I stripped it, and between the air compressor in my garage, and some good cleaning agents, put it back to 'ready for inspection' condition, cleaned and reloaded both mags, and back in the holster...
I would never recomend one of these for a 'range gun', to just put holes in paper...for the fact that have have a short barrel, pretty serious snappy recoil, and a steel top on a plastic bottom, over use is going to cause wear and tear... But if you're looking for a good, concealable, affordable, and very reliable big bore DA/SA auto for personal protection, I would HIGHLY recommend one to anyone...
Best of luck with yours,
