I wonder how the numbers of 'FIT and PROPER' Licensed Firearms users are holding up? - I'd put money on the current 50 page Firearms Licence Application forms and the highly obstructive process having cut the numbers to around 50% of earlier days.
- The 'application form' to apply to join the NZ Police is ONE PAGE.
WHY are NZ's Civilian Police exempted from meeting the same Firearms Licence requirements as citizens to carry their MSSAs and semi-auto Pistols?__________________
SAFETY TIP, you won't ever get a chain-fire if you only shoot single shot pistols eh.
You might say that the study of 'Pocket Pistols' is an obscure topic - in that there is no lying douchebag fraudulent gun broker RL Wilson that spent 30 years writing books making-up false heritage and valuations about early Colts revolvers while stealing the best items from museum collections. - Nobody has ever bothered to falsify and record much history about low cost single shot percussion pistols from the 18th and 19th Centuries.
Gawd but I've read some crap about GRIPS .. one online bloke said he couldn't see any difference between Glock grips and '1911' grips. Gotta be a 'dumbfuck' that one.

Moi - I'd observe that all those early old "flintlock" pistols, - having that slow BLACKPOWDER push recoil give you a chance to hold a secure grip .. nothing like the sharp snap from a modern nitro powered pistol.
The Variables: Can I also say this - If you have 'average' hands then lucky you, - the average gun grip will likely be fine. If you've got tiny little hands then you do have an issue - as all but the smallest guns are going to be too bloody big. And I don't mean, go buy an airweight alloy snubby 357 Magnum.
- And if you've got longer finger bones - you likely will need bigger grips that push the bulk of the gun forward and bring the trigger near to where your trigger finger bends nicely.
There is no way you will be able to shoot a handgun both accurate and fast unless that gun fits your hands. - You might love the looks of a 'Desert Eagle' but if you can't hang-on to it under blast-off you should forget it.

Not all so called "flintlocks" are flintlocks - many are percussion Caplocks.
Many single shot antique guns you will find in New Zealand will be the el cheapo BOXLOCK pattern that experts describe as being of a common, low cost type, of indifferent quality. - As found and offered for sale these are often badly rust corroded and pitted - and, and if of the 'turn-off barrel' type they likely will be seized solid and covered in gouges from vise grip attempts made to unseize them. The inside of the barrel and powder chamber typically are corroded and filthy while the nipples are also likely to be damaged by repeated dry firing .. provided that the mainspring is not broken - which many are.
What are these antiques properly called ?
Boot Pistol, Muff Pistol, Pocket Pistol, Sleeve Gun, Vest Pocket Pistol, "Derringer" are names I've seen used for these carry guns of yesteryear.These 'BOXLOCK Turn-off' Pistols .. may even sometimes mistakenly be called "a Queen Anne pistol" - when a genuine 'Queen Anne' would be a sidelock FLINTLOCK.
There are no legal definitions of what these antiques are properly called - nor are there standards that describe the patterns of their handles .. GRIPS or Stocks:
Cane Handle, Bag Shaped, Slab Sided, Saw-Handle, Birds' Head, Plow Handle, 'Stirrup-type butt-cap with long side-terminals'. - Back then they might be whatever shape the maker fancied.
