ISMI 1911 Springs 

Thunder Mountain Custom is now offering the complete line of ISMI 1911 springs.  

The ISMI Difference
ISMI premium springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then our springs are heat treated, shot peened and stress relieved after winding to enhance performance and durability. Our springs utilize the same design and manufacturing technology as used in IndyCar and Formula One racing. In a typical 500 mile race, a valve spring in an IndyCar will go through more than 2,500,000 compression cycles. Consideration of factors such as modulus, wire diameter, mean diameter, active coils, total deflection, spring relaxation, maximum service temperature, and operating environment; results in you having modern spring technology available for your pistol.


1911 Short Block - 45ACP - Classic 

Our 1911 “Short Blocks” are perfect for do-it-yourself shooter or custom Gunsmiths looking for a head start with our quality components. Our Short Block kits come with a slide, frame, and barrel fit together using the same components and methods we use for our full builds at a fraction of the cost designed to save you time and money on your next project.  We will be adding different Calibers and configurations over the next few months.
