KDGJ, agree with Small bore on the drop locks or hand detachable side locks esp. ref wet weather. Happened to me in the Selous 4 years ago with a Holland, torrential rain for 4 hours walking, lock wouldnt fire. Back in camp, took it out, oiled it, released it, cocked it on a wooden bench, replaced, hey presto, ready to go. All I can say about a Westley Richards single trigger (and I would apply this to all single trigger makers excluding the italians) is what every UK gun maker has told me off the record, 99% of the time no problem but when they they go wrong only the maker should be trusted to fix them. best, Mike
