But you need to carry the parts?
If it comes to the worst I imagine you could manually touch off the powder in the pan with a burning twig or similar?
Would that work so you could still keep a degree of accurancy and hit the target?
With a modern gun, if basically any component breaks, you are out. Imo this is the huge weakness with modern firearms.
Even with a decent home workshop it is virtually impossible to replicate most internal parts. Complex design, specific alloys.
I do all my tuning and fitting of spare parts on my guns, have always done so, and it is becoming more and more difficult.
This specially on standard US made guns, where I feel the quality is in a virtual free fall. Extreme loose fit, no possibility for any adjustments. Weird powdery alloys.
I hesitate to mention them for fear of jinxing them; but Ruger actually seems to be inproving regarding quality (although they're as complex as the rest)
