| Hey guys I was just wondering how much of a job changing out a MSH is? I couldn't stand looking at the cheap ass plastic MSH on my CDP anymore and ordered an ED Brown SS one today. Just looking for tips on the install as I am new to 1911's. |

Very simple to do- 1. Make sure the gun is unloaded. 2. Make sure the hammer is down, ie: not cocked. 3. Take a small punch, and on the convex side of the pin, the one with the dimple, drive out the MSH pin and remove the MSH. 4. Take the MSH and sit it on a table, holding it in your palm. 5. Take a bigger punch, one that will fit in the dimple of the mainspring cap, and push down. It will take some force. 6. Take a small punch or straigtened out paper clip and push out the mainspring retaining pin. 7. Using caution, gently take off the pressure of the mainspring, with the punch and remove the cap, spring and base. 8. Re-assemble in reverse in your new MSH. 9. Re-install in firearm and test. 10. Go shooting!

I'll add a bit: 1. Make sure the gun is unloaded. 2. Make sure the hammer is down, ie: not cocked. Field strip the gun. Slide OFF. This relieves all hammer tension from the spring and makes removal of the housing pin easier. 2A. Use tape, twist ties, or rubber bands to lock the grip safety down. This will hold the sear spring in place and prevent problems from the spring moving out of position. 3. Take a small punch, and on the convex side of the pin, the one with the dimple, drive out the MSH pin and remove the MSH. 4. Take the MSH and sit it on a table, holding it in your palm. 5. Take a bigger punch, one that will fit in the dimple of the mainspring cap, and push down. It will take some force. 4 and 5 alternative: Drive a small finishing nail into a wood block, leaving about 3/4" inch sticking up out of the block. Put the end of the mainspring housing over the nail and press down firmly to relieve tension, then use a small punch to push out the mainspring retaining pin 6. Take a small punch or straigtened out paper clip and push out the mainspring retaining pin. 7. Using caution, gently take off the pressure of the mainspring, with the punch and remove the cap, spring and base. 8. Re-assemble in reverse in your new MSH. 9. Re-install in firearm and test. |
