WTB/WTT Glock 20 10mm or similar larger caliber backup gun

[injunjon]

I'm looking for a Glock 20. I've got a S&W 686-1 4" stainless revolver in 357 magnum with a pachmeyer grip and holster for possible trade if the deal is right. I was going to carry this as a backup during my hunt in December but it is a little too heavy and I'm not a fan of the powder blow back from revolvers. It is a sweet little gun but I am just more of an automatic fan. Let me know what you've got. I'm going to put the revolver up on here as soon as I can get the photographs done.
