I've lost count of the amount of chewed up pistols I've had for repair [rifles too]. These look a good option; however coming across so many problem ones; I've made up a jig which allows me to drill the cap with 2 holes same as on other Originals and then I use my 2 peg wrenches. Not something everybody might do, but I had access to toolroom equipment which gave me the chance to make lots of specialist tools. That said I'm still getting a pair of these and thanks for the heads up.
