Those are selling for anywhere from $100 - $200, depending on condition.
The GT27 was an inexpensive 25 auto, which shot and cycled well, as long as it was kept clean, but if it got dirty, it would hang up often. A lot of those were imported under the name of Excam by Valor Corp out of Hialeah, FL, which used to be one of my suppliers. Being very inexpensive, with new wholesale costs around $50-$75, they were relatively good sellers and I sold alot of these for $100-$125 brand new, in box. So, there is not going to be much value in those today, I would think.
Where can I buy a new firing pin for GT27 in .25cal? Nice little back up gun, my shoots well. Thanks
go to ebay type in excam gt 27 you will find it there
