Even though your gun is a semi auto, and does not fire so soon after chambering a round, since it takes time for the hammer to fall onto the firing pin, you should STILL use the bolt catch device in your bolts to make darn sure that those rollers are FULLY locked before ignition occurs.
Along with the "bolt-stabilizer" (and that the "Firing-Pin-Holder" has been updated with the second cam-surface at the top)......a couple of other things you should check prior to going to the range with a Full-Auto MG42:
1: Condition of "Recouperator-Assembly" to insure that the barrel is returned to the forward position prior to the bolt pushing the next cartridge forward from the feed-tray.
2: Condition of Cam-surfaces in the Trunnion to insure the bolt unlocks correctly.
3: Condition of "locking-slots" in barrel-extension on the barrel (and bore).....and that you have the correct caliber barels for the ammo you are taking to the range.
4: Correct Booster-Cup/"Nozzle" for your caliber "and" that you start with the shorter Barrel-Bearing so that the gun will initially fire slower.
Condition of other parts and lubrication of the gun will be important also....as will condition of belts and ammo.
Taking your spare barrels and bolts with you will be a good idea so that you can check these at the range.
And last.....your paperwork/registration/license.

...bolt catches were not employed in 42s until after the war was over.
