The Titleist Model 100 / Pro 100 Irons is a traditional lofted iron set built around a 38° 7 iron and a 50° pitching wedge. Factory lofts span 20° to 50° across 9 clubs, with gaps ranging from 3° to 4° through the set.

The bars place the whole set on one iron-loft scale. That makes the progression from long-iron distance lofts into scoring and wedge lofts easier to see without making small gaps look artificially huge.

How each Model 100 / Pro 100 Irons loft changes the shot
| Club | Loft | What that loft changes |
|---|---|---|
| 2-iron | 20° | At 20° this is a true top-end distance iron. It will normally launch lowest, run out most and demand the most speed and strike quality in the set. |
| 3-iron | 23° | At 23° this is a true top-end distance iron. It will normally launch lowest, run out most and demand the most speed and strike quality in the set. The gap from the previous club is 3°. |
| 4-iron | 26° | At 26° this remains on the distance side of the set. The loft keeps flight stronger and flatter than the scoring clubs, so carry consistency matters more than the number stamped on the sole. The gap from the previous club is 3°. The next step changes to 4°, so this is a transition point worth checking with real carry numbers. |
| 5-iron | 30° | At 30° this remains on the distance side of the set. The loft keeps flight stronger and flatter than the scoring clubs, so carry consistency matters more than the number stamped on the sole. The gap from the previous club is 4°. |
| 6-iron | 34° | At 34° this is the set’s central control zone. It gives a good read on how aggressively the set is lofted and how much height versus distance the design is asking for. The gap from the previous club is 4°. |
| 7-iron | 38° | At 38° this is the set’s central control zone. It gives a good read on how aggressively the set is lofted and how much height versus distance the design is asking for. A 38° 7-iron puts this set in the traditional loft category. The gap from the previous club is 4°. |
| 8-iron | 42° | At 42° this is into scoring-iron territory. More loft here should increase launch, spin and descent angle, helping the ball stop faster as approach distances shorten. The gap from the previous club is 4°. |
| 9-iron | 46° | At 46° this is into scoring-iron territory. More loft here should increase launch, spin and descent angle, helping the ball stop faster as approach distances shorten. The gap from the previous club is 4°. |
| PW | 50° | At 50° this sits at the wedge end of the stock set. The loft is increasingly about trajectory, stopping power and distance control rather than raw carry. The gap from the previous club is 4°. |
The 38° 7-iron makes this a traditional-lofted set. The 50° pitching wedge is the key checkpoint for the transition into specialty wedges. The most useful test is still real carry spacing, because equal loft gaps do not always create equal yardage gaps.
