I traded a used Mossberg 500 for a Colts Government Model Series 70 45 ACP.
There is nothing original about this weapon. The entire weapon has been modified from sights to magwell. It has even been re-blued.
I have never owned a Series 70. I own 4 Series 80's, so I am not new to the 1911 in and of itself. I am new to the Series 70. Any "do's" and "don'ts" I should know? This one came to me with a plastic shock buffer on the guide rod. I dont know if it belongs there or not. The recoil spring is super stiff making me think someone set this up as a competition weapon and it locks up super tight.
All ideas thoughts and suggestions welcome.

Does it have the series 70 collet bushing still?
Buffer is fine on a range gun, but do replace often. The stiff recoil spring is probably more detrimental to the gun when the slide moves forward than when it goes back.
Sometimes a stiff recoil spring was used to overcome a reliability issue.
Unless you need the gun overstrung, I might swap springs and lose the buffer for the sake of longevity and reliability.

It does still have the Series 70 bushing. And it is TIGHT! A takedown wrench is an absolute must.

There are a few different ways to field strip a 1911 with a tight bushing that don't require a bushing wrench. You can learn them on YouTube. Nighthawk demonstrates an interesting method of complete disassembly that doesn't require a wrench. |

A heavy spring is a typical modification from someone who thinks they know what they’re doing, most of the time. Seldom is a heavier than normal spring needed, and I’ve NEVER seen one used on a competition gun for IPSC/USPSA, because the muzzle dip that occurs when the slide is slammed forward is accentuated with a heavier spring. Normally a competitor will use the lightest spring that will attain reliability and not beat the gun up. A fitted solid bushing would be my first mod to the gun, or a fitted bull barrel and delete the bushing altogether, but that requires further mods. If you decide to run a recoil bushing on the guide rod, make sure and monitor for deformation or splitting as that will affect reliability.

Nighthawk demonstrates an interesting method of complete disassembly that doesn't require a wrench. ***** Trey.... as stated, after the magazine is removed and chamber cleared, here are two ways to field strip pistol (strip slide from frame). 1) Retract slide enough to align disassembly notch with slide stop. Push out slide stop. Pull slide assembly off frame. (Slide is under spring tension.) 2) Retract slide enough to unseat muzzle from bushing. Depress recoil spring plunger enough to rotate bushing. Rotate bushing clockwise to release recoil spring. Remove slide stop & slide. In the absence of a bushing wrench to remove a tight bushing, a crescent wrench works well. Oil or grease these parts prior to reassembly. David Bradshaw |

As indicated, the Series 70 has a collect bushing----Colt’s idea was to increase accuracy without fit-up. In all Series 70 I’ve handled, the bushing is tight only with slide in battery. Retract slide a bit to remove tension on muzzle. Bushing rotationCounter clockwise----remove recoil spring plug & spring Clockwise----remove bushing from slide David Bradshaw |
