Accurising the TSC/GSG 1911
By Vince Bottomley Accurising he TSC/GSG 1911
I’m certainly no expert but from memory, accurising a 1911 involved fitting a ‘match’ barrel with matching barrel-bushing and improving the ‘slide to barrel’ fit. OK, there were a whole series of other ‘hop-ups’, too involved to discuss here – even if I had the knowledge but take a look at the Valmont Firearms website at
www.valmontfirearms.
co.uk and you will see a vast array of goodies to customise your 1911. Hopefully, a whole new discipline will be built around these little pistols
The Tunnel Services GSG 1911 LBP (long barrel pistol) has certainly created something of an “I want one” culture amongst pistol-deprived UK shooters – sorry, make that ‘GB deprived’ – Northern Ireland and the Isle of Man still have their pistols of course...
Anyway – enough of that. If you have recently bought a TSC 1911, you will probably have noticed that one thing is missing – accuracy! OK, they were never meant to be target pistols but the ‘real’ 1911 can be made into an accurate pistol, so why not the GSG?
but first, we gotta get ‘em to shoot! This month, we will look at what I perceive to be the biggest problem and what we can do to fix it. I’m talking about that barrel-bushing – or to be more accurate the ‘bushing to barrel’ fit.
You can see how big the barrel/bushing clearance is!
On a well-tuned 1911, the clearance between these two components will be minimal – a ‘working’ clearance only. On my GSG 1911 this gap measures an alarming 0.03 inches - or 30 thousandths of an inch! Yours may be different but I’m betting it will still be excessive.
