Both of these are .45 cal. I bought the one on top with an extra .36 barrel a couple weeks ago. Bought the one on the bottom last week on gunbroker. Top one has a much prettier stock, but it's cracked near the lock screw. Bottom one isn't cracked anywhere.
I will probably end up putting the .36 barrel on the top one and use it for target shooting since it's so pretty.
The bottom one will be my back-up hunting gun for deer season, since that one has a plain Jane stock.
