Bought my shield in 45 on 3/27/2017. On the field strip 4/10/2017 the recoil spring separated. Guide pin flew over my shoulder large spring hanging in the slide. Evidently the lock ring broke.
called S&W customer service, spoke with a (didn't understand the name) guy who said he would drop one in the mail, 7 - 10 business days.
7 business days later no recoil spring assembly, called again spoke with Jacob (total A$$) same story. Finally 0n 4/18/ 2017 called again 11 business days, spoke with Mark, said he would put it in the mail 2 day priority, gave me an order number, and I should have it by the end of the week 4/21/2017
now 4 /22 no spring assembly, nice looking paper weight. It was an excellent shooter. But probably the last time I deal with S&W. Patience is a virtue I do not possess when dealing with a company with a history as long a Smith.
