I have one. Bought it when they first came out in 98, IIRC. It has been shot infrequently over the years. Almost a year ago I started carrying it. It carries very well. It shoots good to, but it hurts after about 15 rounds of standard .38 Special, and after about 5 rounds of +P. Never fired any +P lead out of it. I have fired lead standard .38 Special and it was a non event. My carry load is the 135gr +P Gold Dot short barrel load.
I have used a brass bush and hoppes to clean it. I have not noticed any ill effects.
All this said I also have a M38 that I like better, but it is not +P rated, so I can practice with the +P more in the 342. This is why it is the one that I carry.
