From different places and for different reasons people decide to get a semi custom or custom flintlock. Let’s not argue definitions but for me a custom flintlock is made to order not from a list of options but from a discussion starting with a blank slate or an original rifle or a group of original rifles. You may have different views so let’s say “non-factory rifle yet to be built”. What I recommend to such customers: 1) People should probably not get a custom flintlock unless they are already experienced flintlock shooters or know experienced flintlock shooters they can go to the range with, unless they want a wall hanger. 2) One should know how a flintlock gun works, how to disassemble, clean, lube, and re-assemble all the way down to stripping the lock. 3) one should be very familiar with the ins and outs of getting good flintlock ignition. 4) A customer should have seen the builders work in their hands. And they should know what they like and want versus looking for “is this good or bad?” on a forum. 5) whenever possible it’s best to buy a built gun. Many custom makers have built guns. Maybe slightly used and the previous customer died or wanted another one now that is different. 6) if you are going to wait for a gun to be built add 50% to the predicted wait time. Sorry, the world is what it is despite what we demand is “only right”. Deal with reality. 7) expect to pay up front for parts and to be notified when they are all ready. Some outfits that provide semi-custom guns may not require this. 8) understand your builder goes to shows, has a family, and is not in call 24/7 for all customers. But insist that you’ll be informed when your build is started and when it is expected to be done. 9) Specify EXACTLY which parts you MUST have and understand they may not be available. If you want a .45 Colerain swamped A profile barrel with round grooves 42” long and a Rice 44” swamped barrel in B weight with square grooves will not do, insist the builder verify he’s using your choice of barrel. Same for a Chambers Late Ketland lock. Understand he might not get one for 8 months. If another lock will not do, wait or find one and send it to the builder. He or she cannot create supplies made by others. 10. You should receive just what you paid for. A good example of that builder’s work that is reliable and functions really well in expert hands. As you can tell I do not believe anyone is always right, including customers. Some customers are great and some are amazingly difficult. Ask any home improvement contractor.
