Field strip vs. Detail strip
Field strip - -
Draw slide to the rear until the disassembly notch lines up with the small tab atop the slide stop. Maintain a good hold on the slide and press the slide stop out from the right. Ease the slide forward until it comes off the front of the frame.
Remove recoil spring and guide to the rear. Turn the slide so that the muzzle points upward. Rotate the barrel bushing until it can be pulled out the front of the slide. Shake the recoil spring plug out the front of the slide. Turn the barrel link so it points toward rthe muzzle and pull the barrel out of the slide from the front.
This completes field stripping. Fouling may be wiped or brushed from the frame feed ramp, the standing breech, and the locking area of the slide. Barrel is free so the bore may be cleaned from the rear and the exterior wiped clean.
I could describe how to detail strip the frame assembly, but reassembly is a bit more complicated than for field strip. Normally, the frame is not disassembled, and this is seldom required if only jacketed factory ammunition is fired.
Reassembly - -
Replace barrel in slide. Replace recoil spring and its guide in the slide, with the barrel link turned toward the muzzle. Run the slide onto the frame rails from the front, all the way to the rear. Look through the slide catch and align the barrel link with the hole. Replace the slide stop axle through the hole, capturing the barrel link. The slide stop must be pressed into the frame cut just so, that the detent plunger holds it in place. A narrow, flat blade screwdriver is a help in doing this. Replace the barrel bushing in the front of the slide, turning it between coils of the recoil spring, and leaving it turned to the other side. Place the recoil spring cap on the recoil spring and press the assembly all the way in. Turn the bushing so that it captures the recoil spring plug.
Anyway, if you do acquire a 1911-type, you'll want to get at least one decent reference book or manual.
Best,
