Originally got the 9mm w/ thumb safety model in early 2015 for $362 out the door. Sold it and just recently purchased the 9mm non-thumb safety model for $374 on Gunbuyer (349+$25 transfer fee from my LGS). Now that I have the experience of having shot the Thumb Safety model, I am happy with the price, and feel its value is worth more than that.
I think my first one was $379 (they day the came out) and my second was $319 (the day they came out no manual safety). My last one was $299 on sale with LEO discount. They just keeping getting less expensive so I keep buying them!
Still scanning gunbroker for used or parts only shield 9mm. No luck. Would love to get ahold of a spare barrel without buying a whole new gun. They must be holding up pretty good.
$376.99 for a thumb safety 40 S&W shipped. A local shop charges $17 for transfers. Every local shop says they can't keep shields in stock, and apparently they are on back order in 9mm from the manufacturer. Luckily I wanted the 40.
