Last year, I bought one kit, made in Spain. As this pistol pleased me and though that it would enjoyable to assemble and polish.
Barrel channel was 1/4" out of axis, fitting was more than light milling and need wood paste to fill the gap and so on for trigger, putting hammer and nipple well together seems impossible without rebuilding the stock, I didn't understood how I could fit all together to get something operationnal.
So I bought the same from the same brand but "ready to shoot out of the box":
Enjoy-it each time I bring-it to the range.
Sold the "kit" 85% in box with paper for 5$ (a gift maybe valuable, for 5$ you know what you get) to a friend (well advertised about difficulties). Last time we speak of this little thing, he hadn't any complaint against me and he though to buy a new "finished" one !.
Maybe a lemon, don't read so bad thing about their kit usually, that's why I gave a try.
I like hand working but now I'll stay far from kit. Refinishing and adjustement on used guns or evn new one are enough to me.
At the opposit of this "snubby", you will find someone who make me dreaming about kit:
